Plain English summary of protocol
Background and study aims
We aim to conduct a clinical study to investigate the potential benefits of treating latent tuberculosis infection (LTBI) in individuals residing in developing countries with a high incidence of both tuberculosis (TB) and LTBI. Specifically, we are interested in understanding whether treating LTBI can have positive effects on the health of patients with chronic kidney disease (CKD). Our study will explore various health aspects, including assessing whether LTBI treatment reduces the risk of developing active TB, enhances muscle strength (indicative of nutritional status), improves the body's response to insulin, and regulates inflammation levels in the body.
Who can participate?
Patients with Latent Tuberculosis Infection (LTBI), and Chronic Kidney Disease (CKD)
What does the study involve?
Patients will be randomly assigned to one of two groups, similar to flipping a coin. One group will receive daily anti-TB drugs (Isoniazid 5mg/kg and Pyridoxine 20mg) for six months, while the other group will receive no treatment.
The study will span three years, with patients seen by study staff every three months during their usual Kidney Foundation clinic visits. Routine blood tests recommended by their clinic doctor will continue, and any special study-related tests will be provided at no cost to the patients.
What are the possible benefits and risks of participating?
As a participant in this research study, patients may not benefit directly; information from this study will help other people with CKD in the future, whether we should treat LTBI. We already know in many developed countries, in accordance with WHO (World Health Organization) guidelines, LTBI is treated with anti-TB drugs.
The Isoniazid and Pyridoxine given in this study rarely cause any serious adverse effects. Uncommon side effects that you might encounter include anorexia, nausea, vomiting, abdominal discomfort, persistent fatigue, or weakness, dark-coloured urine, pale stools, or jaundice. If side effects are severe, especially if there is evidence that the liver function is affected, they will be asked to stop treatment. We will be monitoring their liver and other tests every 3 months. If they become symptomatic while on treatment they will be asked to contact a member of the research study group immediately (details listed below).

| Scientific title | A single centre, open-label, randomised clinical trial evaluating Isoniazid Monotherapy treatment to Prevent Accelerated Chronic kidney disease in latent Tuberculosis in a High Incidence Country. |
| Study acronym | IMPACT-HIC |
| Study objectives | Whether treatment with 6 months’ isoniazid plus pyridoxine have any effect on the rate of change in eGFR of CKD patients (eGFR 20-60) with Latent Tuberculosis Infection (LTBI) |
| Ethics approval(s) |
Approved 21/03/2023, Institutional Ethical Committee, Kidney Foundation Hospital and Research Institute (Plot5/2, Road-1, Mirpur-2, Dhaka, 1216, Bangladesh; +880 2-9024074; rashid@bol-online.com), ref: KFHRI/ECC-002/2023 |
| Health condition(s) or problem(s) studied | Chronic kidney disease with latent tuberculosis infection |
| Intervention | Intervention - IMP with 6 months isoniazid 5mg/kg/day maximum daily dose 300 mg (plus pyridoxine 20 mg) Comparison group – The alternative group will receive no treatment compared with the intervention group as per current practice in Bangladesh. Patients will then be randomized into one of two groups. One group will receive IMP daily, for 6 months while the second group will receive standard care (no specific treatment for LTBI) for 6 months. The randomization envelopes will be grouped into 20 Blocks (10 envelopes within each group). Each group will contain 5 envelopes specifying IMP and 5 no treatment in random order. Each envelope will be identified by the Block number and kit number The study will comprise of four stratified groups of patients: A. Diabetic and No Glomerulonephritis B. Diabetic and Glomerulonephritis C. Non-Diabetic and Glomerulonephritis D. Non-Diabetic and No Glomerulonephritis |
| Intervention type | Drug |
